Ask them, when you say "no evidence", do you mean that you have personally reviewed all of the evidence, and decided that none of it was credible?
or do you mean that you have literally never seen any of the evidence, and therefore you are absolutely ignorant about all of the evidence?
Because I’m pretty sure the video of an election worker pulling a box full of ballots out from under a table cloth, has never been “debunked”.
I just go after their messiah. "I was just really surprised how much more popular Biden was with Blacks and liberals than Obama. Especially in the swing states."
